'Advance to next unread message' Toggle?

Laura Ess

Years ago when I was using Thunderbird there was "fix" for the Advance to next message pop-up, which appears when you press N or P to move to the next/previous message, and that message is on another account. If I remember correctly I think the fix was going into the "debug list" where you could change individual settings if you knew the name of the setting, and set it to off.

Anyway I couldn't find that list at all in the current version (probably a good thing). Is there a setting somewhere or fix where I can turn off this popup?

Chosen Solution

Thunderbird has a hidden preference setting that controls this behavior.

  1. Open Thunderbird Settings. At the top right of the Thunderbird window, click the menu button ≡ > Settings
  2. Scroll to the bottom of the General panel and click Config Editor...
  3. In the search box, paste: mailnews.nav_crosses_folders
  4. Double-click the preference (or click the edit pencil icon) to change its integer value:
  5. Set the value to 0 and press Enter.

Once set to 0, pressing N will continuously jump across folder and account boundaries directly to the next unread message without interruption.

Aha, the Config Editor. -- that's what I used before, but I couldn't remember what it called. Did as instructed and works perfectly. THANK YOU!
